How to read this table
- Sale history is not collected for any jurisdiction yet — no source Big Map uses supplies it. It's a planned addition, not a hidden feature.
- Available means every parcel has the field. Partial means some did, or the field is looked up live for some parcels only. Not available means none did. Government source values can still be inaccurate.
- Freshness describes how often Big Map refreshes, not the age of every government record. The Carolinas and DC Metro refresh weekly; statewide North Carolina is refreshed on demand.
- Expand Evidence under any jurisdiction for the sources behind that row. Parcel counts come from the latest quality snapshot. Fields looked up when you select a parcel are noted in the row detail.
